It did not permit the user to switch back to the Finder once it was launched. Multiple selection of individual items in a Custom Install as opposed to an Easy Install had to be done -- trickily -- by pressing the Shift key.

The Apple Installer evolved under System 7. Instead of being a dialogue box, it became a separate window, with title bars, resizable windows, and even info buttons and the hierarchical triangular list view copied from the Finder. It also offered the option of a clean install.

It now is an "umbrella" installer, including routine that had to be otherwise independently executed, such as disk checks. Whereas the Classic Mac OS used to include the Installer application along with the to-be-installed software bundle, Mac OS X includes only the software bundle as a package.

This takes a long time to do and sucks up your internet bandwidth in the process, as each download could take two hours or more. To make matters even worse, if you download the latest macOS update as soon as Apple makes it available, download times are likely to be even slower while Apple's servers struggle to keep up with initial demand.

You can save yourself a lot of hassle by saving the macOS installer after downloading it the first time. That way, you can use the same macOS installer to update as many Mac computers as you need without multiple downloads. The macOS installer file may also be helpful if something goes wrong with your Mac in the future. If you decide to "start fresh" and reinstall macOS, you'll need the macOS installer to do so.

However, you still need to quit the macOS installer when it starts up after the download completes.

Although older versions of the macOS installer are also located on the App Store, they don't turn up from a normal search. Download the macOS installer as you would any other app: click Get , enter your Apple ID password, and wait for the download to complete. But you can still download them as disk images directly from Apple's website.

After doing so, open the disk image to find the Mac OS X installers:. Unlike most files, the macOS installer isn't located in the Downloads folder after you download it.
